As much as it's an interesting idea, I have a couple of reservations.
Firstly, you would be selling this to mostly teenages and engineers who largely seem incapable of correctly putting in pedals or bottom brackets let alone assembling a frame. I could imagain a lot of comeback from people cocking up the assembly.
I also think it would be difficult to to guarentee a perfectly aligned frame, you said you used a jig, not many people will have access to one and could end up with a wonky frame.
Changing the geo with bent tubes, I don't think there are many people who could correctly calculate the exact bend redii to get the wanted geo, not with out upsetting some other angle anyway.
I am all for thinking of new ideas, but this seems to be trying to fix a problem that doesn't exist. I would much rather know what I want then buy a frame that matches (or go custom with a cheap steel jobbie). Having a frame with more potential points of failure, risk of not being straight, heavier and without wanting to be too rude, not as good looking just doesn't sound like a great idea to me.
Congrats on getting this far though.
